What Are Humidifiers and What Do They Do?

Humidifiers are standalone or whole house mechanical systems designed to increase the moisture levels in the air by spewing out steam or water vapor.

This amazing machine converts water in its reservoir into healthy, breathable vapor, improving the overall air quality in the room.

According to, a respected health-focused website, humidifying indoor air reduces dryness around the user’s mucous membrane, throat, skin, and lips.

Additionally, these air saturating devices can even ease various symptoms associated with the common cold or flu.

A whole-house humidifier (central humidifier) sends out water vapor to the entire house via the heating and air conditioning system. Other types of humidifiers are best suited to humidifying the air in one room or location rather than the entire house.

This category of humidifiers are called standalone humidifiers, and this humidifier reviews site dedicates a slew of posts on these standalone units.

How Humidifiers Work

Humidifiers produce and release water vapor into the air to improve humidity. Water in a reservoir is absorbed by a wicking filter. A fan blows air over the filter, releasing some of the water in the form of vapor.

The moisture becomes part of the air, thus humidifying the room or house. Humidifiers may also work by boiling water to release steam or breaking and releasing water droplets. It all depends on the type of humidifier you have.

Humidifier vs Air Purifier vs Dehumidifier

A humidifier increases a room’s humidity levels. An air purifier removes irritants (like bacteria, dust, mold, dust mite, pollen, pet dander, mildew, and viruses) from the air.

A dehumidifier, on the other hand, removes excess humidity from the air. It is possible to buy an air purifier/humidifier combo, air purifier/dehumidifier combo, or a humidifier/dehumidifier combo.

However, a combo device may have one of the functions working better than the other one. That may compromise the overall functionality of the device.

5 Reasons to Buy a Humidifier

Humidity levels tend to drastically dip in the cold season. A humidifier can help improve humidity and benefit users in the following ways:

  • Faster Healing: By increasing relative humidity levels in your home, a humidifier lubricates the nasal passage, making it possible to heal from allergies, asthma, and colds.
  • Relieving Sinusitis: In dry air, sinuses do not function and drain properly. Thus, improving a room’s humidity can relieve sinusitis and congestion.
  • Preventing Nosebleeds: Lubricating the nasal cavity also goes a long way to alleviating nosebleeds. That is where a humidifier comes in.
  • Preventing Skin Dryness: Living in a dry house is one of the quickest ways to dehydrate your skin. A humidifier restores moisture in the air, thus helping you have soft, supple skin.
  • Alleviating Snoring: Moistened air is necessary to prevent dryness in the throat, relieving snoring. A humidifier improves air quality, making it easier to sleep next to a snoring partner.

5 Types of Humidifiers

Even though humidifiers serve the same function, they are available in different types including the following:

1. Central Humidifiers

Central humidifiers are usually integrated into a home’s heating and air conditioning system. Even though more expensive than the other types, they act as whole-house humidifiers. They don’t directly emit steam but subtly improve air humidity.

2. Impeller Humidifiers

Impeller humidifiers have fast rotating disks that split water into tiny particles before releasing it into the air. They are less costly and more child friendly than other devices. The devices create no steam and thus won’t cause any burns. However, they are room humidifiers rather than serving the whole house.

3. Evaporators

Evaporators work by blowing moisture off a moistened filter. Funs blow air through the filter, releasing moisture into the air. Even though affordable, these devices only act as room humidifiers. They release too much moisture and may adversely affect asthmatic individuals.

4. Ultrasonic Humidifiers

Using ultrasonic vibrations, this type of humidifiers spread cool mist through the air. They are also known as cool mist humidifiers even though some versions act as warm mist humidifiers. The cost depends on the size of the humidifier.

5. Steam Vaporizers

Steam vaporizers rely on electric heating to convert water into steam, which humidifies the air. They are portable and costlier than the other types of humidifiers. They should be kept away from kids to prevent burns.

Can a Humidifier Make You Sick?

Yes. A humidifier that wicks impure water may end up releasing mold and mildew into the air, leading to some health issues.

When pathogens enter your sinus cavities and lungs, they will cause asthma and other complications. That’s true for vaporizers and evaporative humidifiers.

Also, ultrasonic humidifiers may release minerals in the forms of “white dust” into the air, causing injury to the lungs of infants.

Cool Mist vs Warm Mist Humidifiers, What’s Better?

Cool mist humidifiers are those that release cool moisture into the air. They include ultrasonic and evaporative humidifiers. Since they hardly produce noise, they are perfect for use in the bedroom. They have filters, which they use to remove impurities from the water vapor.

Warm mist humidifiers, on the other hand, work by releasing heated steam into the air.  They can increase a room’s humidity levels quickly, providing quick relief from respiratory conditions. Hot steam can kill most pathogens including bacteria, mold, viruses, and mildew.

Both have clear benefits. So, the type of humidifier you buy boils down to your budget and personal preferences. A cool air humidifier will cost much less than its warm air counterparts.

How to Size a Humidifier for a Room

Every humidifier has a rating for the room it can cover in square footage. That’s why you should size it up by measuring the length and width of the room. With a 700 square feet rating, a humidifier can work in a small room and bedroom. To avoid the growth of bacteria and mildew, avoid buying a humidifier whose rating is too high.

How to Clean a Humidifier

After unplugging the humidifier, disassemble it. Pour up to two cups of vinegar into the water tank. Turn it around until the tank’s interior is completely wet. Connect the tank to the base to drive vinegar down into the water reservoir. Allow it to stand for up to 20 minutes to loosen mineral buildup.

After emptying the tank and reservoir of minerals scrub the surface with a brush. Wipe smaller parts with a sponge or cloth dipped in white vinegar. Thoroughly rinse all the parts, air dry, and reassemble. Don’t wash the wick filter as you could damage it. If the filter isn’t working, replace it with a new one.
